edit 4 : installed wicd-client from help.ubuntu.com/community/WICD . disconnection continues and so switched back to network manager again
issue is persistent

edit 5 : took a backup and installed windows 7 for one day , wifi worked fine implying hardware is working fine

edit6 : contacted dell support in case to be sure to know if the card was ok .they ran diagnostic and assured hard ware is working fine

edit 7 : after all the efforts , i realized that there is something missing with respect to the linux kernel itself, and so i intalled r8168-dkms via synaptic packet manager and the wifi is up since 235 minutes
but again the next day drop after 30 minutes of use

edit 8 : of all the above things that i have tried edit : 7 is the most stable, how ever i am not sure of the solution as disconnection persists

edit 9 : blacklisted r8169 by following in /etc/modprobe.d/r8168-dkms.conf

# if the aliases above do not work, uncomment the following line
# to blacklist the whole r8169 module
#blacklist r8169

by uncommenting as advised to

# if the aliases above do not work, uncomment the following line
# to blacklist the whole r8169 module
blacklist r8169

I am trying to install Nvidia driver on my laptop with installed Ubuntu 16.04. The graphic card is NVIDIA GeForce GTX 780M. I followed the instruction on the Nvidia website and downloaded the driver from here: http://www.nvidia.com/download/driverResults.aspx/136120/en-us. The installation process went well, the OS recognized the driver, but the colors in some programs have been changed: magenta shade is appeared. There is an example of same picture before and after installation the driver:

My system is frequently, but intermittently locking up. I am unsure of what to do next to troubleshoot and/or whether I should report this as a bug. Advice would be appreciated. Note that my question is similar to one previously posted at radeon 0000:02:00.0: ring 0 stalled for more than 10492msec that has yet to be responded to.

My system intermittently locks up every few days. When that happens, the screen goes to black, then returns. At that point, the time on the clock indicates that the screen is frozen, but audio continues to play for 30 seconds to a minute. The keyboard and mouse do not affect what’s being displayed, but I can Alt – SysRq – REISUB to restart.

[Edit:] Based on @MichaelBay ‘s suggestion, I ran the Checkbox graphics card tests and everything passed. I also I ran MemoryTest. No errors were found after 3 passes. Finally, I loaded Psensor to check the GPU temperatures, but there are no GPU readings.

As a result of the operation, it creates a new device named Unknown device without children.

When I install my driver from Device Manager -> Add Legacy Hardware, everything is fine and a new SampleClass device with two children (a generic mouse and a HID compliant device) is created, so I don’t think it is because my *.inf file lacks something.

I am using Lenovo x1 carbon 3rd generation with ubuntu 18.04, The touch pad is behaving weird like, If you drag the pointer down to a specific point and removes the finger from the touchpad then the pointer jumps to a random position.

An example will be closing a browser tab, Drag the pointer x and remove the finger off the pad, The pointer jumps to a random position.

After several hours of frustration, I’m giving up.

The default trackpad driver of the Asus UX303U is truly catastrophic. I downloaded ELAN driver 16.21.13.3 which is fantastic, but I am not able to turn on two finger scrolling. (On Windows 10 Home 64 bit.)

There’s a lot of online content about this, but nothing works for me.

Going to Settings and then Touchpad, I get the Your PC has a precision touchpad. Scrolling down there are many options and among them is Drag two fingers to scroll under Scroll and zoom. Checking them has no effect.

Under Related settings, going to Additional settings and then to the ELAN tab, the options button is greyed out as depicted below. So I cannot access that either.

When I run ETDAniConf, I get the blank window below. Running ETDSimpleUI gives an ETDSimpleUI has stopped working error.

I am sure you’ve heard of the old “uninstall a driver and it will reinstall” trick

well, i’ve uninstalled multiple drivers just now and none of them have reinstalled by themselves. fortunately, they were all under CD/DVD Drives in device manager, but, holy cow, i dont even know what some of those were. Any help with this one? Windows 10 here. MSI Gaming notebook (model: GL62 6QF). Obviously my disc drive doesn’t work now.

Edit: The most logical next step for me here was to turn on automatic driver updates in Advanced System Settings. It was already on. I’m completely stumped.

Ever since Microsoft released Windows 8 and then Windows 10, Intel stopped releasing new drivers for their USB 3.0 ports integrated into their newer chipsets. They let Microsoft do the work. I have a Z270 motherboard and the Intel(R) USB 3.0 eXtensive Host Controller is currently removable.

From the Device Manager, the problematic drivers:

Windows Update does say I have the latest driver. With Intel not releasing any new driver, what are my options to make those ports non-removable in Windows 10, considering I obviously can’t remove them without going into my BIOS settings?

I’m trying to get an NVIDIA 970M GPU working after something went wrong with the drivers. I’ve tried purging and manually wiping the system of everything nvidia/cuda related and reinstalled both from the ppa:graphics-drivers/ppa and from the NVIDIA installer.

Both approaches fail to get the system to use the NVIDIA GPU (as evidenced by nvidia-prime which I use to switch to the NVIDIA GPU, but after reboot it always returns to the onboard intel GPU).

What I’m trying to understand now is exactly what configuration in
ubuntu is used to configure which graphics drivers are actually
loaded?

How do I actually query the kernel to understand what drivers it
thinks are available, and which drivers it is using?

Are there logs other than dmesg (with show nothing special) that I
should be looking at to debug this?
